1 Claim, 3 Drawing Figures PATENTEDJAH 1a 1913 QALDH F? QUL WW ail/(9% BACKGROUND OF THE INVENTION It is often desirable to have available means for effccting immediate and temporary repairs to mobile machinery and equipment. This is especially difficult to achieve in situations where welding is required to accomplish the repairs.

An illustration of an application where this occurs quite often is in the military. Military vehicles are often damaged under circumstances which necessitate abandoning the vehicle either permanently or until repair facilities are available at the site of the damage or necessitates towing the vehicle to a repair depot. Risk of injury to the operator is increased if he attempts to operate the vehicle in its damaged condition. Damage to components relating to steering, axles, frame and body are among those which occur quite frequently.

To meet this need, prior art devices have been developed, however these devices are such as to require more than one part to be at the same location atthe same time thus increasing logistics problems and operator training.

SUMMARY OF THE INVENTION A further object of the present invention is to utilize a suitable compound for the heat producing means such that it may be'activated by either a match or exposure to the atmosphere.

These together with other objects and advantages, which will become subsequently apparent, reside in details and construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof,

wherein like numerals refer to like parts throughout, and in which;

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:

FIG. 1 is a sectional view of a welding device constructed in accordance with and embodying the present invention.

FIG. 2 is a fragmentary sectional view of another welding device constructed in accordance with and embodying the present invention.

FIG. 3 is a fragmentary sectional view of another welding device constructed in accordance with and embodying the present invention.

DETAILED DESCRIPTION OF THE INVENTION Referring now in more detail and by reference characters to the drawings which illustrate practical embodiments of the present invention, FIG. 1, is a sectional view of welding device, I, constructed in accordance with and embodying the resent invention.

Welding device, 1,1s shown In G. I, IS seen to comprise elongated cylindrical member, 2, sealing means, 3, handle means, 4, and heat producing material, 5.

Cylindrical member, 2, is provided with chamber, 6, said chamber being provided with outlet port, 7, which is shown in FIGS. 2 and 3. Pyrotechnic material, 5, is contained within chamber, 6, and sealed therein by sealing means, 3.

Various types of heat producing or pyrotechnic materials may be used in the present invention. Particular materials may be used which ignite upon exposure to atmosphere while others may be used which may be ignited by means of a spark or flame from a conventional match.

Handle means, 4, is merely provided as a convenient method for holding welding device, 1, while in use.

Cylindrical member, 2, is constructed of conventional welding or brazing material depending upon the particular application.

In the use of welding device, 1, sealing means, 3, is removed and heat producing material, 5, is ignited. As the heat producing material, 5, burns, the exterior end of elongated cylindrical member, 2, melts as heat is supplied simultaneously to member, 2, and the surface of a part being repaired.

Many different operations, such as brazing, welding, cutting, may be covered by simple variations in parameters such as the length or material of member,

2, or in the type of heat producing material being used. Welding device, 1, may be used under water as well as in the atmosphere.

As shown in FIGS. 2, and, 3, the exterior end of cylindrical member, 2, may be shaped to improved performance of welding device, I.

It should be understood that changes and modifications in the form, construction, arrangement, and combination of the elements of the welding device and methods of making and using the same may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

Having thus described my invention what I claim and desire to secure by United States Letters Patent is:

l. A welding device comprising,

an elongated rod, said rod provided with a an elongated chamber therein which extends the length of said rod and communicates with an outlet port at one end of said rod, said rod being constructed of conventional welding rod material,

handle means operably mounted on the opposite end of said elongated rod,

heat producing means operably disposed within said elongated chamber such that when said heat producing means is ignited heat is provided at said outlet port which may be directed and which progressively melts said rod from said outlet port to said handle, and

removable sealing means operably mounted on said rod, said removable sealing means adapted to seal said chamber. 

1. A welding device comprising, an elongated rod, said rod provided with a an elongated chamber therein which extends the length of said rod and communicates with an outlet port at one end of said rod, said rod being constructed of conventional welding rod material, handle means operably mounted on the opposite end of said elongated rod, heat producing means operably disposed within said elongated chamber such that when said heat producing means is ignited heat is provided at said outlet port which may be directed and which progressively melts said rod from said outlet port to said handle, and removable sealing means operably mounted on said rod, said removable sealing means adapted to seal said chamber.
